Well the good news is that if any stereotypical comic fan was ever connected to the Flash Force they'd be able to run for a least a day or two before having to eat. Also why the hell does Batman even need to be on roof tops? All the assholes he fights are on the street and the awkwardness of the different roof designs and heights seems as if it would slow him down more than anything. So give up the dream nerds it's never going to happen according to science. Now magic on the other hand...
